[Effect of temporary interruption of blood flow through the major intracranial vessels on the outcome of surgical treatment of arterial aneurysms].

During operations for clipping an aneurysm, the blood flow along the artery supplying this aneurysm was temporarily arrested in some patients to prevent intraoperative hemorrhage. It has been proved that the arrest of blood flow along the main vessel for more than 20 minutes during an operation in the acute period of subarachnoidal hemorrhage, particularly in the presence of a vascular spasm, aggravates the course of the postoperative period and is conducive to the lethal outcome.
